[0352] The wireless mobile communication system can support UE to establish multi-access connections with the network through a variety of different access technologies (ATs), and use these ATs to establish (single access) PDU sessions or multi-access PDU sessions.

[0353] Access technologies (AT) include: terrestrial 3GPP access technologies (such as NR, E-UTRA, UTRA, NR RedCap), satellite (non-terrestrial) 3GPP access technologies (such as NR (LEO), NR (MEO), NR (GEO), NR (OTHERSAT)); non-3GPP access technologies (such as trusted WLAN access, untrusted WLAN access, etc.).

[0354] A (single access) PDU session refers to a PDU session that uses only one AT to transmit data; a multi-access PDU session has access branches established on different ATs and can use different ATs to transmit data.

[0355] The UE can establish dual connectivity using a terrestrial 3GPP access technology (e.g., NR) and a satellite (non-terrestrial) 3GPP access technology (e.g., NR(LEO)), establish one or more (single access) PDU sessions on NR, and simultaneously establish one or more multi-access PDU sessions using NR and NR(LEO). Alternatively, the UE can establish dual connectivity using two terrestrial 3GPP access technologies (e.g., NR and E-UTRA), or can establish dual connectivity using a terrestrial 3GPP access technology (e.g., NR) and a non-3GPP access technology (e.g., trusted WLAN access).

[0356] In this application, "multi-access" and "multi-connection" refer to the scenario where the UE registers to the network through multiple ATs.

[0357] The energy consumption of communication equipment refers to the energy consumed by communication equipment to support communication operations and complete communication tasks. Energy consumption can be calculated by measuring the power of the equipment over a period of time. The energy consumption of the entire communication system is the sum of the energy consumption of all communication equipment in the system. The energy efficiency of the communication system / communication equipment reflects the efficiency of energy consumption and can be defined as the ratio of the amount of data transmitted to energy consumption, or the ratio of the communication area covered / served to energy consumption. Energy efficiency can be targeted at the entire network, subnet (such as a wireless access network, a single network device, a communication site (such as a data center), a terminal, etc.

[0358] The 5G network can guide the UE to select which or multiple access technologies to transmit application / service data by sending policies or rules (such as UE Routing Selection Policy (URSP) and Access Traffic Steering Switching Splitting (ATSSS) rules) for transmitting application / service data on (single access) PDU sessions and / or multi-access PDU sessions to the UE. However, the current relevant policies and rules do not take into account the energy consumption and energy efficiency factors of the UE or network.

[0359] When a UE uses multiple access technologies to connect to a network and / or transmit data at the same time, it will increase the energy consumption of the network and the UE. The existing technology lacks an effective solution for reducing the energy consumption of the network and the UE or improving energy efficiency in UE multi-access scenarios. For example, when a UE establishes multi-access connections and sessions through different access technologies (ATs), how does the network or UE decide to process (e.g., release or modify) existing connections and / or sessions to reduce network or UE energy consumption?

[0360] Based on the above technical problems, the embodiments of the present application propose a communication method, device and storage medium, which control the UE to use the first access technology AT and / or the second AT for communication through a first multi-access related strategy, thereby reducing the impact of multi-access on the energy consumption of the network and / or UE, and improving the energy efficiency and performance of the network and UE.

[0491] 1. The UE uses the first access technology (AT1) to access NG-RAN1 and initiates registration with the network (e.g. AMF). The registration request carries the UE's capability indication of supporting multiple access. The AMF processes and accepts the UE's registration request. For details of the process related to multiple access, see steps 2-6.

[0492] 2.AMF obtains the subscription data from UDM, which includes the subscription information related to UE multi-access.

[0493] Specifically, for the UE / user, the UE multi-access related subscription information includes one or a combination of the following information:

[0494] (1) Allowing UE to use multiple ATs simultaneously (which can be indicated by AT type).

[0495] (2) Allow the use of multi-access network slices (which can be indicated by a single network slice auxiliary selection information S-NSSAI).

[0496] (3) Allowing the use of multiple access data networks (which can be indicated by the data network name DNN), such as a specific local access data network LADN.

[0497] 3.AMF sends a policy request or event report to PCF, which carries the information that the UE accesses / registers through AT1 and the indication that the UE supports multiple access.

[0498] 4. The PCF sends an event report to the AF, which carries the information that the UE accesses / registers through AT1 and the indication that the UE supports multiple access.

[0499] 5. AF replies to PCF with the policy for application / service transmission on multiple access, i.e., the policy for application / service transmission on AT1. For a specific application / service, the policy for application / service transmission on multiple access includes one or a combination of the following information:

[0500] (1) Allow or prohibit multiple ATs to be used simultaneously (can be indicated by AT type).

[0501] (2) Allowing or prohibiting the use of network slices for multiple access transmission (which can be indicated by single network slice auxiliary selection information S-NSSAI). And / or,

[0502] (3) Allow or prohibit the use of data networks with multiple access transmissions (which can be indicated by the data network name DNN and the data network access identifier DNAI).

[0503] 6. PCF replies to AMF with the UE multi-access related policies, i.e., the policies for transmitting applications / services on AT1. Specifically, the UE multi-access related policies may include one or a combination of the following information:

[0504] (1) The UE cannot use multiple ATs simultaneously.

[0505] (2) When there are connections with other ATs, AT1 is released (eg, satellite access technology).

[0506] (3) ATs arranged by priority: When a UE uses a high-priority AT to access, it releases the access of low-priority ATs.

[0507] (4) Multiple ATs that a UE can use simultaneously.

[0508] (5) Application / service multi-access transmission policy. For details, see step 5. The PCF may determine the policy based on the information provided by the AF (see steps 4-5) or the PCF local policy.

[0509] (6) Timer timer1 is used to instruct the network to release or modify the PDU session of AT1 (or a branch of a multi-access PDU session) and / or release the connection of AT1 only when the UE successfully accesses the network through another AT (e.g., AT2) for a period exceeding timer1 (e.g., 2 minutes).

[0510] (7) Time period or area information, used to indicate that the PDU session of AT1 (or a branch of a multi-access PDU session) is released or modified, and / or the connection of AT1 is released, within the specified time period or area.

[0511] 7. The UE establishes one or more PDU sessions (or branches of a multi-access PDU session) through AT1.

[0512] 8. The UE uses the second access technology (AT2) to access NG-RAN2 and initiates a registration request to the network (e.g., AMF). The UE provides the GUAMI of the AMF in step 1 to NG-RAN2 (e.g., the RRC Setup Complete message carries this parameter), and NG-RAN2 selects the AMF based on the GUAMI, i.e., the same AMF performs access management (including registration, service requests, etc.) of the UE through AT1 and AT2.

[0513] AMF determines whether to accept the registration request of UE through AT2 based on the UE subscription data. For example, if the network slice that UE requests to access allows UE to use multiple access, then AMF accepts the registration request of UE through AT2.

[0514] 9.AMF sends a policy request or event report to PCF, which carries the information that the UE accesses / registers through AT2 and the indication that the UE supports multiple access.

[0515] 10. The PCF sends an event report to the AF, which carries the information that the UE accesses / registers through AT2 and the indication that the UE supports multiple access.

[0516] 11. The AF replies to the PCF with the policy for transmitting the application / service on multiple accesses, that is, the policy for transmitting the application / service on AT2.

[0517] 12. PCF replies to AMF with UE multi-access related policies, that is, it replies to AMF with the policy for transmitting applications / services on AT2.

[0518] 13.AMF determines to release or modify the PDU session (or branch of the multi-access PDU session) established by the UE using AT1 based on the policy provided by the PCF or the AMF local policy.

[0519] Specifically, the network function entity NF (such as PCF, AMF, SMF, AF) can determine the network strategy or contract information related to multi-access according to the energy-saving requirements or energy consumption / energy efficiency of the network of different ATs. Including: the above network strategy or contract information can be dynamically adjusted according to the current energy consumption / energy efficiency of the network or UE of different ATs, the statistical information of the past energy consumption / energy efficiency, and / or the predicted information of the future energy consumption / energy efficiency. Specifically, it can include one of the following methods:

[0520] (1) NF (e.g., PCF, AMF, SMF, AF or NEMF (Network Energy consumption and efficiency Management Function)) obtains network energy consumption / efficiency analysis information (including statistical or forecast information) of one or more ATs from NWDAF. NEMF can determine the network energy consumption / efficiency information of one or more ATs based on the analysis information and / or network configuration.

[0521] (2) NF (eg, PCF, AMF, SMF, AF) determines the above multi-access related strategies based on the above analysis information, or based on the network energy consumption / energy efficiency information of one or more ATs provided by NEMF.

[0522] For example: if the network supporting a specific AT has (relatively) high energy consumption or (relatively) low energy efficiency, or the network supporting a specific AT (such as a satellite access network) has (relatively) high energy saving requirements, the NF (such as PCF, AMF, SMF) sets the release of the AT in the multi-access related strategy, or sets the AT to a lower priority, or uses the AT to transmit applications / services with (relatively) low energy consumption.

[0523] 14. AMF (or PCF) triggers SMF to transfer / switch (all or part of) sessions or QoS flows on AT1 to AT2. Or, AMF (or PCF) triggers UE to transfer / switch (all or part of) sessions or QoS flows on AT1 to AT2.

[0524] 15. Optionally, if the connection of AT1 is to be released, the AMF initiates a deregistration procedure of AT1 to the UE, or the UE initiates a deregistration procedure of AT1.

[0525] Example 2:

[0526] Figure 4This is the second schematic diagram of the multi-access control signaling interaction provided in the embodiment of the present application, such as Figure 4 As shown, multiple access control may include the following steps:

[0527] 0. The UE uses AT1 to access NG-RAN1 and initiates a registration request to the network (e.g. AMF). The AMF processes and accepts the UE's registration request. The UE establishes one or more PDU sessions (or branches of multi-access PDU sessions) through AT1. After that, the UE uses AT2 to access NG-RAN2 and initiates a registration request to the network (e.g. AMF).

[0528] 1.AMF sends an event notification to SMF, which carries the information that the UE accesses or registers through AT2.

[0529] Alternatively, if the AMF determines to trigger the release or modification of the PDU session (or a branch of the multi-access PDU session) established by the UE using AT1 based on the multi-access related policy provided by the PCF or the local multi-access related policy of the AMF, then:

[0530] If the AMF determines to trigger the release of the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1, the AMF initiates a session release request (or a multi-access PDU session modification request) to the SMF, which carries the identifier of the PDU session to be released.

[0531] If the AMF determines to trigger the modification of the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1, the AMF initiates a session update request or a session transfer request to the SMF, which carries the identifier of the PDU session to be modified and the source access type (i.e., AT1); if the AMF determines to trigger the transfer of all or part of the sessions or QoS flows (corresponding to specific applications / services) of AT1 to AT2, the request message also carries the target access type (i.e., AT2) and / or information about the UE's access or registration through AT2.

[0532] 2.SMF obtains the contract data from UDM, which includes the session management contract information related to UE multi-access.

[0533] Specifically, for the UE / user, the UE multi-access related session management subscription information includes one or a combination of the following information:

[0534] (1) Multiple ATs can be used simultaneously (indicated by AT type).

[0535] (2) Allow the use of multi-access network slices (which can be indicated by a single network slice auxiliary selection information S-NSSAI).

[0536] (3) Allow the use of multi-access data networks (which can be indicated by the data network name DNN).

[0537] 3. The SMF sends a policy request to the PCF, which carries the source access type (ie, AT1), the target access type (ie, AT2), and / or information about the UE accessing (or registering, or establishing / modifying a PDU session) through AT2.

[0538] 4. Optionally, the PCF sends an event report to the AF, which carries information that the UE accesses (or registers, or establishes / modifies a PDU session) through AT2.

[0539] 5. Optionally (if step 4 is executed, this step is executed), the AF replies to the PCF with the application / service multi-access transmission policy. For a specific application / service, the application / service multi-access transmission policy includes one or a combination of the following information:

[0540] (1) Allow or prohibit multiple ATs to be used simultaneously (can be indicated by AT type).

[0541] (2) Allowing or prohibiting the use of network slices for multiple access transmission (which can be indicated by single network slice auxiliary selection information S-NSSAI). And / or,

[0542] (3) Allow or prohibit the use of data networks with multiple access transmissions (which can be indicated by the data network name DNN and the data network access identifier DNAI).

[0543] 6. PCF replies to SMF with the UE multi-access related session management policy. Specifically, the UE multi-access related session management policy may include the following information:

[0544] (1) The UE cannot use multiple ATs simultaneously when establishing a PDU session.

[0545] (2) When there are connections with other ATs, the PDU session (or a branch of a multi-access PDU session) of AT1 (eg, satellite access technology) is released.

[0546] (3) ATs arranged by priority: When a UE accesses using an AT with a high priority, the PDU session (or a branch of a multi-access PDU session) of an AT with a low priority is released.

[0547] (4) A UE can use multiple ATs simultaneously when establishing a PDU session.

[0548] (5) Application / service multi-access transmission policy. See step 5. The PCF may determine the policy based on the information provided by the AF (see steps 4-5) or the PCF local policy.

[0549] (6) Timer timer1 is used to instruct the network to release or modify the PDU session of AT1 (or the branch of the multi-access PDU session) only when the UE successfully accesses the network through other ATs (such as AT2) for a period exceeding timer1 (such as 2 minutes). (Note: SMF can determine whether this condition is met based on the event notification of UE access / registration in AT1 and other ATs received from AMF.)

[0550] (7) Time period or area information, used to indicate that the PDU session of AT1 (or a branch of a multi-access PDU session) is released or modified only within the specified time period or area.

[0551] 7. According to the multi-access related session management policy provided by PCF or the local multi-access related session management policy of SMF, SMF determines to release or modify the PDU session established by UE using AT1, and / or transfer all or some sessions or applications / services of AT1 to AT2. SMF sends a message transmission request to AMF, including the following situations:

[0552] (1) If the SMF determines to release the PDU session (or the branch of the multi-access PDU session) established by the UE using AT1, the request carries the PDU session resource release information (or multi-access PDU session resource modification information) sent to NG-RAN1 and the PDU session release command (or multi-access PDU session modification command) sent to the UE.

[0553] (2) If the SMF determines to transfer the PDU session of AT1 (or all QoS flows of the multi-access PDU session branch) to AT2, the request carries PDU session resource release information (or multi-access PDU session resource modification information) sent to NG-RAN1 and PDU session resource establishment information (or multi-access PDU session resource modification information) sent to NG-RAN2.

[0554] (3) If the SMF determines to modify the PDU session (or a branch of a multi-access PDU session) established by the UE using AT1 and transfer some QoS flows (corresponding to specific applications / services) in the session to AT2, the request carries PDU session resource modification information sent to NG-RAN1, PDU session resource establishment information (or multi-access PDU session resource modification information) sent to NG-RAN2, and a PDU session modification command sent to the UE.

[0555] Alternatively, if step 1 is a session release request, the SMF sends a session release response to the AMF, which carries the PDU session resource release information sent to NG-RAN1 and the PDU session release command sent to the UE.

[0556] If step 1 is a session update request or a session transfer request, the SMF sends a session update response or a session transfer response to the AMF, which carries PDU session resource modification information or PDU session resource release information (or multi-access PDU session resource modification information) sent to NG-RAN1, PDU session resource establishment information (or multi-access PDU session resource modification information) sent to NG-RAN2, and a PDU session modification command sent to the UE.

[0557] 8-13.AMF forwards the PDU session resource modification information or PDU session resource release information to NG-RAN1 based on the message sent by SMF, forwards the PDU session resource establishment information (or multi-access PDU session resource modification information) to NG-RAN2, and forwards the PDU session modification command or PDU session release command to the UE through NG-RAN1 or NG-RAN2. NG-RAN1, and NG-RAN2 (if NG-RAN2 receives the PDU session resource establishment information (or multi-access PDU session resource modification information)), initiates radio resource reconfiguration to the UE. The establishment of the session (or multi-access PDU session branch modification) on NG-RAN2 / AT2 and the modification or release of the session (or multi-access PDU session branch) on NG-RAN1 / AT1 are completed, thereby transferring all or part of the sessions (or multi-access PDU session branches) or QoS flows of AT1 to AT2.

[0558] Example three:

[0559] Figure 5 This is the third schematic diagram of multiple access control signaling interaction provided in the embodiment of the present application, such as Figure 5 As shown, multiple access control may include the following steps:

[0560] 1. When triggered by one or a combination of the following conditions, the PCF decides to send or update the multi-access related UE policy to the UE.

[0561] (1) The UE requests the network for UE policies related to multiple access. The request message carries the UE multiple access capability indication and the AT types (e.g., AT1, AT2) that the UE supports for simultaneous access. The AMF forwards the UE's request to the PCF.

[0562] (2) The PCF receives an event report / event notification from the AMF regarding UE registration. For example, the UE registers through AT1 and the UE registers through AT2. Based on this, the PCF determines that the UE registers to the network through multiple ATs.

[0563] (3) The PCF receives the transmission policy (update) of the service / application on a specific AT (eg, AT1, AT2) sent by the AF, and accordingly determines that a multi-access related UE policy needs to be sent or updated.

[0564] (4) The PCF receives the multi-access related subscription information (update) sent by the UDM / UDR, and determines that the multi-access related UE policy needs to be sent or updated. For the multi-access related subscription information, see Example 1 and Example 2.

[0565] 2-3. PCF sends / updates the multi-access related UE policy to UE through AMF. AMF forwards the multi-access related UE policy to UE.

[0566] Specifically, the multi-access related UE policy may include one or a combination of the following information:

[0567] (1) The UE cannot use multiple ATs simultaneously;

[0568] (2) Release AT1 when there are connections with other ATs (e.g., satellite access technology);

[0569] (3) ATs arranged by priority: When a UE uses a high-priority AT to access, it releases the access of low-priority ATs.

[0570] (4) Multiple ATs that a UE can use simultaneously.

[0571] (5) Application / service strategy in multi-access transmission. See Example 1 and Example 2.

[0572] (6) Timer timer1 is used to indicate that the UE will release or modify the PDU session of AT1 (or the branch of the multi-access PDU session) and / or release the connection of AT1 only when the UE successfully accesses the network through another AT (for example, AT2) for a period exceeding timer1 (for example, 2 minutes).

[0573] (7) Time period or area information, used to indicate that the PDU session of AT1 (or a branch of a multi-access PDU session) is released or modified, and / or the connection of AT1 is released, within the specified time period or area.

[0574] 4. The UE receives the UE policy related to multiple accesses. If the UE is currently registered to the network through multiple accesses, such as AT1 and AT2, the UE determines to transfer all or part of the sessions or QoS flows on AT1 to AT2 according to the UE policy related to multiple accesses.

[0575] 5. The UE initiates PDU session establishment and / or session modification on AT2, and PDU session modification or release on AT1, thereby transferring all or part of the sessions or QoS flows of AT1 (e.g., PDU session 1, QoS flow 1 of PDU session 2) to AT2.

[0576] Example 4:

[0577] Figure 6This is the fourth schematic diagram of the multi-access control signaling interaction provided in the embodiment of the present application, such as Figure 6 As shown, multiple access control may include the following steps:

[0578] 1. The UE locally determines a multi-access related policy. The policy may include one or a combination of the following information:

[0579] (1) UE cannot use multiple ATs simultaneously.

[0580] (2) When there are connections with other ATs, AT1 is released (eg, satellite access technology).

[0581] (3) ATs arranged by priority: When a UE uses a high-priority AT to access, it releases the access of low-priority ATs.

[0582] (4) Multiple ATs that a UE can use simultaneously.

[0583] (5) For specific applications / businesses:

[0584] Allow or prohibit the simultaneous use of multiple ATs;

[0585] Allow or disallow the use of network slicing for multi-access transport; and / or,

[0586] Allow or disallow the use of multiple access transports on the data network.

[0587] (6) When the UE uses AT1 and other ATs at the same time, specific applications / services are prioritized or prohibited from being transmitted on AT1 and / or other ATs. For example: 1) voice applications / services are preferentially transmitted on AT1 (which can be indicated by application identifiers or service types), and data applications / services are preferentially transmitted on other ATs (such as AT2); 2) video applications / services are prohibited from being transmitted on AT1 (or other ATs).

[0588] (7) Timer timer2 is used to instruct the network to release or modify the PDU session of AT1 (or a branch of a multi-access PDU session) and / or release the connection of AT1 only when the UE subsequently successfully accesses the network through another AT (e.g., AT2) for a period exceeding timer2 (e.g., 3 minutes).

[0589] (8) Time period or area information, used to indicate that the PDU session of AT1 (or a branch of a multi-access PDU session) is released or modified, and / or the connection of AT1 is released, within the specified time period or area.

[0590] The UE may determine the UE multi-access related strategy based on the energy consumption / energy efficiency of the UE accessing a specific AT. Specifically, the UE may determine and dynamically adjust the strategy based on the energy consumption / energy efficiency statistics of the UE's previous access to a specific AT, and / or the energy consumption / energy efficiency prediction information of the UE's future access to a specific AT. The method for the UE to obtain the energy consumption / energy efficiency statistics or prediction information of the UE at a specific AT is shown in Example 5.

[0591] 2. If the UE is currently registered to the network through multiple accesses, such as AT1 and AT2, the UE determines to transfer all or part of the sessions or QoS flows on AT1 to AT2 according to the UE policy related to the multiple accesses.

[0592] 3. The UE initiates PDU session establishment and / or session modification on AT2, and PDU session modification or release on AT1, thereby transferring all or part of the sessions or QoS flows of AT1 (e.g., PDU session 1, QoS flow 1 of PDU session 2) to AT2.

[0593] Example five:

[0594] Figure 7 Schematic diagram of access related information analysis signaling interaction provided by an embodiment of the present application, such as Figure 7 As shown, the analysis process of access related information may include the following steps:

[0595] 1. The NF or UE sends an analysis information request or subscription message to the NWDAF to request or subscribe to the energy consumption / energy efficiency analysis information of the network or UE for a specific AT.

[0596] Specifically, the analysis information request or subscription message carries the following parameters:

[0597] Analysis ID / Type: indicates that energy efficiency or energy consumption related analysis is performed. For example: Analytics ID = EnergyEfficiency, or Analytics ID = Energy Consumption.

[0598] Target of analysis report: one or more terminal identities (e.g. SUPI) or terminal group identifiers, or "any UE".

[0599] The analysis filtering information is shown in Table 1. In particular, the analysis filtering information includes an AT type, which is used to indicate a request / subscription to the energy consumption / energy efficiency analysis information of a network or UE of a specific AT.

[0600] Analytical accuracy.

[0601] Target analysis time, indicating the time range of the requested statistical or forecast information.

[0602] Notification association identifier and notification target address, used to subscribe to analysis information.

[0603] Reporting Thresholds can be used for anomaly detection, for example: ReportingThresholds = maximum energy consumption, or maximum energy consumption ratio, or lowest energy efficiency. The maximum energy consumption or maximum energy consumption ratio can be used to instruct the NWDAF to report relevant analysis information when the statistical or predicted value of the energy consumption of the network or UE using a specific AT reaches or exceeds the threshold. The lowest energy efficiency can be used to instruct the NWDAF to report relevant analysis information when the statistical or predicted value of the energy efficiency of the network or UE using a specific AT reaches or falls below the threshold.

[0604] Table 1 Analysis and filtering information

[0605]

[0606] 2. NWDAF collects data related to energy consumption / energy efficiency of the network or UE for a specific AT as input data based on the analysis information request or subscription message, which is used to train the energy consumption / energy efficiency model of the network or UE for the specific AT and obtain the requested analysis information.

[0607] NWDAF can collect relevant input data from OAM, network function entity NF (such as network energy efficiency management function (NEMF), access network AN (such as NG-RAN), AMF, SMF, UPF, etc.) or UE. Specifically, the type and description of the input data are shown in Table 2.

[0608] Table 2 Type and description of input data

[0609]

[0610]

[0611] The NWDAF uses the collected input data to train the energy consumption / energy efficiency model of the network or UE of the specific AT, and further obtains the energy consumption / energy efficiency analysis information of the network or UE of the specific AT based on the trained model and the input data.

[0612] Specifically, the obtained energy consumption / energy efficiency analysis information of the network or UE of the specific AT is shown in Table 3. The analysis information may include: statistical information of network or UE energy consumption / energy efficiency for the specific AT, and / or prediction information of network or UE energy consumption / energy efficiency for the specific AT.

[0613] Table 3 Output analysis information

[0614]

[0615] 3. The NWDAF sends a reply or notification message to the NF or UE, which carries the energy consumption / energy efficiency analysis information of the network or UE for the specific AT.

[0616] 4. By (repeatedly) executing steps 1-3, the NF (e.g., AF, PCF) or UE obtains energy consumption / energy efficiency analysis information of networks or UEs for different ATs (e.g., AT1, AT2) from the NWDAF. Based on the energy consumption / energy efficiency analysis information of networks or UEs for different ATs, the NF or UE determines a multi-access-related strategy (see Examples 1 to 4).
